coral id please

[Nihoa]

im not usually one to buy first ask questions later but occassionaly you spot a good deal and i know i can pass it along to another reefer should i be unable to care for it. generally, we have very similar things in our tank anyway.

this was sold to me as a dented brain but i have my doubts. any other opinions?



and while we are at it, this was sold to me as "some sort of brain thing" for dirt cheap and i figured id pounce on it. i cant tell if its a favia or perhaps an acan?
